Abstract
The utility model discloses an arc extinguishing field, comprising a housing and a plurality of arc extinguishing grates, wherein the arc extinguishing grate at the lowest position is equipped with an arc ignition angle inclined, extending downwards and arranged at the tail end near an externally connected fixed contact. Since the arc extinguishing grate at the lowest position is equipped with an arc ignition angle inclined, extending downwards and arranged at the tail end near an externally connected fixed contact, the e arc extinguishing grate may igniting arc from the fixed contact directly, not like the traditional arc extinguishing system; in addition, an arc ignition member is individually arranged, therefore the arc extinguishing system is easy in assembly operation, and the whole manufacture cost of the arc extinguishing system is effectively reduced.
Description
Technical field
The utility model belongs to the arc extinguishing technical field, is specifically related to a kind of arc-extinguish chamber.
Background technology
Fig. 1 and Fig. 2 have shown a kind of traditional arc quenching system that is used for breaker of plastic casing, and this kind arc quenching system comprises fixed contact (5), striking part (6) and the arc-extinguish chamber (4) that is provided with fixed contact (51); Described arc-extinguish chamber (4) comprises housing (1) and is embedded in a plurality of arc extinguishing grid pieces (2) in the housing (1); The basic configuration of described striking part (6) is the V font, and on fixed contact (5), the other end points in the arc-extinguish chamber (4) arc extinguishing grid pieces (2) of below to the one end by screw; This kind arc-extinguish chamber (4) must with the supporting use of external striking part (6), reserve installation site and installing hole so need go up to striking part (6) at fixed contact (5), can increase the manufacturing process and the manufacturing cost of fixed contact (5), also wasted material.
Summary of the invention
The purpose of this utility model provides a kind of arc-extinguish chamber comparatively easy and the whole cost of reduction arc quenching system of operating when the assembling arc quenching system.
The technical scheme that realizes the utility model purpose is: a kind of arc-extinguish chamber comprises housing and a plurality of arc extinguishing grid pieces that are embedded in the housing; Being positioned at, an arc extinguishing grid pieces of below is provided with the arc leading angle that inclination is extended down at its end near external fixed contact.
In the such scheme, an arc extinguishing grid pieces that is positioned at the top also is provided with the arc leading angle that inclination is extended up at its end near external fixed contact.
In the such scheme, described arc leading angle is that the part plate body bending of this arc extinguishing grid pieces forms.
The utlity model has positive effect: in (1) the utility model, by an arc extinguishing grid pieces of below is provided with the arc leading angle that inclination is extended down at its end near external fixed contact being positioned at, make it can be directly from the fixed contact striking, thereby no longer need as traditional arc quenching system, a striking part is set separately in addition, thus comparatively easy and can effectively reduce the manufacturing cost of arc quenching system integral body in the time operation of assembling arc quenching system.

Embodiment
(embodiment 1)
Fig. 3 to Fig. 5 has shown a kind of embodiment of the present utility model, and wherein Fig. 3 is a kind of perspective view of the present utility model; Fig. 4 is a kind of application schematic diagram of arc-extinguish chamber shown in Figure 3; Fig. 5 is a kind of cutaway view of arc quenching system shown in Figure 4.
Present embodiment is a kind of arc-extinguish chamber, sees Fig. 3, comprises housing 1 and a plurality of arc extinguishing grid pieces 2 that are embedded in the housing 1; Being positioned at, an arc extinguishing grid pieces 2 of below is provided with the arc leading angle 3 that inclination is extended down at its end near external fixed contact 51.In addition, for blow-out better, an arc extinguishing grid pieces 2 that is positioned at the top also is provided with the arc leading angle 3 that inclination is extended up at its end near external fixed contact 51.
The part plate body bending that described arc leading angle 3 is these arc extinguishing grid pieces 2 forms.
Fig. 4 to Fig. 5 has shown a kind of concrete application mode of the present utility model, sees Fig. 4 to Fig. 5, and this arc quenching system comprises arc-extinguish chamber 4 and is provided with the fixed contact 5 of fixed contact 51; Described arc-extinguish chamber 4 comprises housing 1 and a plurality of arc extinguishing grid pieces 2 that are embedded in the housing 1; Described each arc extinguishing grid pieces 2 is arranged on the same side of fixed contact 51; Being positioned at, an arc extinguishing grid pieces 2 of below is provided with the arc leading angle 3 that inclination is extended down at its end near fixed contact 51.An arc extinguishing grid pieces 2 that is positioned at the top also is provided with the arc leading angle 3 that inclination is extended up at its end near external fixed contact 51.The part plate body bending that described arc leading angle 3 is these arc extinguishing grid pieces 2 forms.
In the present embodiment, by an arc extinguishing grid pieces 2 of below is provided with the arc leading angle 3 that inclination is extended down at its end near external fixed contact 51 being positioned at, make it can be directly from the fixed contact striking, thereby no longer need as traditional arc quenching system, a striking part is set separately in addition, thus comparatively easy and can effectively reduce the manufacturing cost of arc quenching system integral body in the time operation of assembling arc quenching system.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
